Filling foam composition, foam filling member, and filling foam

Abstract

A filling foam composition contains a polymer, 4,4′-oxybis(benzenesulfonylhydrazide), an amine compound (except urea compound) having a melting point of 40° C. or more, and an organic peroxide, and the amine compound is mixed in an amount of 5 parts by weight or more per 100 parts by weight of the 4,4′-oxybis(benzenesulfonylhydrazide).

1. A filling foam composition comprising a polymer, 4,4′-oxybis(benzenesulfonylhydrazide), an amine compound having a melting point of 40° C. or more, and an organic peroxide,
 wherein the amine compound is mixed in an amount of 5 parts by weight or more per 100 parts by weight of the 4,4′-oxybis(benzenesulfonylhydrazide). 
 
     
     
       2. The filling foam composition according to  claim 1 , wherein the amine compound comprises dicyandiamides and/or dicyclohexylamine salts. 
     
     
       3. The filling foam composition according to  claim 1 , wherein the polymer is an ethylene-vinyl acetate copolymer. 
     
     
       4. The filling foam composition according to  claim 1 , wherein the organic peroxide is dicumyl peroxide. 
     
     
       5. The filling foam composition according to  claim 1 , wherein the 4,4′-oxybis(benzenesulfonylhydrazide) is mixed in a range of 5 to 30 parts by weight per 100 parts by weight of the polymer. 
     
     
       6. The filling foam composition according to  claim 1 , wherein the amine compound is mixed in an amount of 200 parts by weight or less per 100 parts by weight of the 4,4′-oxybis(benzenesulfonylhydrazide). 
     
     
       7. The filling foam composition according to  claim 1 , wherein the organic peroxide is mixed in a range of 0.1 to 10 parts by weight per 100 parts by weight of the polymer. 
     
     
       8. A foam filling member comprising a filling foam composition, and a mounting member mounted to the filling foam composition, and attachable in an interior space of a hollow member,
 wherein the filling foam composition comprises a polymer, 4,4′-oxybis(benzenesulfonylhydrazide), an amine compound having a melting point of 40° C. or more, and an organic peroxide, and the amine compound is mixed in an amount of 5 parts by weight or more per 100 parts by weight of the 4,4′-oxybis(benzenesulfonylhydrazide). 
 
     
     
       9. A filling foam obtained by foaming a filling foam composition,
 wherein the filling foam composition comprises a polymer, 4,4′-oxybis(benzenesulfonylhydrazide), an amine compound having a melting point of 40° C. or more, and an organic peroxide, and the amine compound is mixed in an amount of 5 parts by weight or more per 100 parts by weight of the 4,4′-oxybis(benzenesulfonylhydrazide).
